To aZZ whom it mat concern:

Be it known that I, CLARENCE'OTIS WHITE, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin, in the State of Minnesota, have invented certain new and usefullmprovements in Ironing-Machines, of which the following'speeification is a full, clear, and exact description, reference being also had'to the accompanying drawings, in Which- Figure 1 is a side elevation. Fig. 2 is a front elevation, and Fig. 3 is a plan view, of the machine complete. Figs. 4 and 5 are enlarged detail views of the inclined padded roll. Fig. 6 is a detached sectional view of the combined hollow shaft and heated rolls. Fig. 7 is an enlarged perspective view of a section of the spring-ring for securing the fabric to the padded roll. Fig. Sis an enlarged sectional view of the combined tight and loosepadded roll. Fig. 9 is a cross-section on thelinewm ofFig. 8. Fig. 10 is an enlarged View of one of the clutchcollars on the shaft G. Fig. 11 is a side view, and Fig. 12 is a top view, enlarged, of the clutch-operating collars; and Fig. 13 is afront' View of one of the same. Fig. 14 is a perspective view of the wedge-frame for operating the collars shown in Figs. 11, 12, and 13. Fig. 15 is an enlargedperspective view of a section of one of the padded rolls, illustrating the manner of securing the padding fabric to the roll.

A is the frame, upon which a table, B, is mounted.

a G (3 are two standards upon the table B, in

which a horizontal hollow shaft, D, is journaled. One end of this shaft (see Fig. 6) is formed with an enlarged hollow drum or roller, E, cast in one piece with the shaft, and the other end supplied with a smaller drum, F, either cast in one piece therewith or screwed or otherwise secured thereon. These rollers E F are adapted to be heated by gas-jets or other means from the inside, in the ordinary manner, and will each be provided with vents h h in their outer ends. The outer ends of the rolls are sunken in the center, as shown at z" '5 in Fig. 6, so that any soot, lamp-black, or other product of the combustion'of the gas will gather upon these sunken parts and not blacken or soil the work being ironed.

G is another shaft, journaled by one end in the standard 0 below the shaft D, and by the other end in a smaller standard, 0 near the center of the tableB, as shown. This shaft G is provided with a worm-gear, H, by a worm-pinion, H on a horizontal shaft, H", secured in suitable bearings (in the table B.

H* is a beltpulley on the outer end of the shaft H by which the latter is driven. the shaft G is a gear, H engaging with a pinion, H, on the shaft D. By this means the revolution of the shaft H will communicate motion to the shafts G and D and revolve them in opposite directions. ing larger than the gear and pinion H, the shaft D will be revolved faster than the shaft G.

Running loosely upon the shaft G outside the standard 0, is a padded roll, K, having conical cavities in its ends around the shaft, in

which conical collars a (6 fit, as shown in Fig. 8. These collars are arranged to slide along the shaft G, but revolve with the shaft by a feather and key, as shown in Fig. 10. Outside the collar to the shaft G is provided with a nut, of, or other means for preventing the collar from running off from the end of the shaft, and between the collar a and the standard 0 two collars, 11 0 are mounted loosely upon the shaft. are cut away obliquely toform inclined or wedge-surfaced shoulders, as shown at c c in Figs. 11, 12, and 13, and over the collars, an oblong frame, L, is arranged with two wedgeshaped ribs, y, on its interior fitting against 8 5 the wedge-shaped shoulders 0, so that the moving of the frame L downward will move the collars b b away from each other along the shaft G, and the moving of the frame upward will allow the collars to approach each other. By this arrangement, if the frame L be pushed downward, the collar lb :will be crowded over against the standard 0, and the collar b, will be crowded over againstthe conical collar a and force the latter inagainst the padded roller K, and also force the latter against the collar a, so that the constantlyrevolving collars a ctwill act as a frictionclutch to connect the revolving shaft G with the loose'padded roll and revolveit at the loo same speed as the shaft.

d is a rod actuated bya treadle, (7?, by which driven 5 5 The gear H be- 65 The inner surfaces of these collars b b 80 the frame L may be drawn downward to operate the clutch, while a screw, 0, enables the box. by which the shaft G is j ournaled in the standard to be adjusted higher or lower to regulate the pressure between the rolls. By this arrangement I am enabled torevolve the roll E against the roll K at a different rate of speed in polishing cuffs and similar laundry-.

'4 F, is a padded roll formed of two oppositelyfabric composing the padding is inserted and inclining parts, M M", the junction of the two parts being opposite the outer face or end of the roll E. This arrangement forms a V-shaped cavity in which to form or break down the neckbands of shirts, &c., and to assist in folding turn-down collars and similar articles.

N is a rod connecting the box by which the shaft G is journaled in the standard 0 with a treadle, N so that the roller M M may be held up in contact with the roller F. The rolls K and M M are each provided with a groove, y, (see Fig. 15,) in their faces parallel with their axles, in which one end of the held therein by a strip, f. The fabric is then wrapped a number of times around the rolls to secure the requisite'flexibility of surface. By this means the fabric will not turn upon the rolls by the pressure, and will be securely held in place by the strip and groove. Upon the ends of the roller K circular grooves are formed, in which spring rings m, having overlapping ends, are adapted to fit, and provided with spursm as shown in Fig. 7, so that when the cloth or other fabric composing the padding of the roll is stretched over the roll and also over the channels, and the rings m stretched over the cloth above the channels and released, their reaction will cause their spurs m to catch the cloth and draw it down into the channels and hold it firmly in place and with a smooth outer surface.

In placing the padding upon the roll M M two pieces of the proper width and shape are wrapped around their respective sections of the roll and secured by the strips 1 and the ends folded over the inner ends and the two parts M M and the latter secured upon the shaft G and drawn together by the nut r. This secures the cloth at the junction of the two parts, while their outer ends are secured by spring-rings m m" in the same manner as the cloth is secured upon the roller K.

The shaft H extends across the table 13, and is provided with a small smooth-surfaced roller, R, running in surface-contact with another larger-surfaced roller, R journaled in a water-tank, It. These rolls form a dampening device, which will be operated by the same power that runs the other parts of the machine.

Having described my invention and set forth its merits, what I claim is- I 1. In an ironing-machine, the combination of a shaft D, having an internally-heated ironing-roll, E, thereon, a shaft, G, permanently geared to the shaft-D, a padded roll, K,

loose on the shaft Gand in frictional contact with the ironing-roll E, and a clutch, whereby the roll K is made to revolve with the roll E or with the shaft G, substantially as and for the purpose specified.

2. The combination of a shaft, D, having two internally-heated ironing-rolls, E F, thereon, shafts G G having a cylindrical padded roll, K, on one, and a conical padded roll, M, on the other, and the supporting-frame, substantially as and for the purpose herein specified.

3. In an ironing-machine, aroll having channels around its ends, and spring-ringsm, having spurs m, and suitable padding covering said rolls, substantially as shown.

4. The combination of the supporting-frame, the shaft I), having an ironing-roll, E, thereon, shaft G, gears H H, padded roll K, conical collars a a wedge-surfaced collars b b", frame L, having wedge-ribs 9 g, and means for moving the said frame, substantially as and for the purpose herein specified.

5. The combination of the hollow shaft D, having ironing-rolls E F thereon, shaft G, shaft G having padded rolls K M thereon,

connecting-gear H- Hfldamping-rolls R It",

the shaft H at right angles to the shaft G, and worm-gear H H connecting the shafts G and H substantially as and for the purpose herein specified.

' 6. The roll E, provided with channels encircling its ends, and a longitudinal groove in the surface of the roll connecting said channels, in combination with a strip to fit into said longitudinal groove, spring-rings to fit into said channels, and the padding fabric, substantially as and for the purpose specified. In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CLARENCE OTIS WHITE.
